Concrete CMS 9 CONCRETE cookie value change

Hello team,

I recently installed concrete 9 successfully on our web server. I tried logging in with the admin credentials that I created during the setup and I was able to log in. I refreshed the page and I was logged out.

I checked the browser for the site cookie and I noticed that when I login, the CONCRETE cookie value changes after a second and when I refresh the page, I am no longer logged in.

I am using Cloudflare for the DNS. I created a page rule and cache rule that will prevent Cloudflare from caching the site, but I am still facing the same issue.

Any suggestion on this will be helpful. Thanks!

Try this. Go to:


and turn off “Log out user if their IP changes”

Thank you very much, your suggestion fixed the issue.

It really should be the default setting but alas, it is not.
